The invention relates to folding metal windows and has for its object toprovide a window of this character which is both air tight and moistureproof.

5 A further object is to provide a window 1n which the parts may befolded to the sides and permit of substantially the entire area of theterfering with the other half; it being cus-V tomary in windows of thistype to have to vopen one side before the other half can be K moved. l Astill further object is to provide a simple means for locking eitherhalf of the window in any desired position.

Still another object is to provide a means for automatically locking thewindows in their closed position so that if the windows were closed andone forgot to operate the locking bolts they could not be opened fromthe outside.

Other advantages are indicated below. lo Referring to the accompanyingdrawings forming a part hereof and illustrating the invention:

Fig. 7 is a fragmentary elevation, the handle being in section, of oneof the Cremorne bolts used for locking the window in different position.This view shows the Window locked in its closed position;

Fig. 8 is a fragmentar detail sectional view taken on line 8-8 of ig. 2;and

Figs. 9 and 10 are fragmentar detail sectional views of the snap boltsuse for locking the window. These views are taken on line 9-9 and line10-10, respectively, of F1g. 2. Referring again to the drawings, thereference numerals 11 designate the side members of the frame and 12 theupper and lower frame members.

Hinged at 13 to the side frame members are side sash members 14 ofsection 15 of the folding window. The side frame members 11 are providedwith continuous ribs or flanges 16 which in the closed position ofthewindow as shown in Fig. 2vcontact with the Sash members 14 and form anair tight and moisture proof joint.

The opposite side sash members 17 ofthe sections have hinged thereto at18, on the interior side of the windows. side sash members 19 ofsections 20 of the folding window. The hinges 18 are preferablycontinuous hinges from the top to the bottom lof the window. The sidesash members 17 of the sections 15 are likewise provided withvcontinuous ribs or flanges 21 which cooperate with the side sashmembers 19 of the sections 20 so asto exclude air or moisture when thewindow is closed.

The other side sash members of the sections 20 are'designated 23 and 24and act as the meeting rails when the Window is in its closed position.The side sash member 23 has a plurality of ribs or anges 25 whichcooperate with suitable parts on the side sash members 24 to make thewindow air tight and moisture proof when in its closed position.

susv

The upper and lower frame members 12 are provided with cross membersextending from side to side. These cross members 30 are secured inposition by screws 31 or other suitable means and have continuous andlower sash members 33 of the sections 15 and 20, see Fig. 4, areprovided witliribs or flanges 34 to cooperate with suitable parts on theupper and lower frame members.

Secured tothe upper and lower parts of the sections 20, lpreferably atthe top and bottom of the meeting rails 23 and 24 are rollers or studs36 which are slidably mounted in the tracks or guideways 32. The .tracksor guideways 32 areprovided with slight jogs 37 (see Fig. 3) at theircentral portion so as to give the meeting rail 24 a slight outwardmovement just prior to it contacting with the rail 23 and insure againstany possible interference.

It will be apparent from the foregoing description an'd an inspection ofthe drawings that both halves of the folding window may be readilythrown to the position indicated in the left hand part of Fig. 3 andthat .s a maximum window opening without any obstructions whatever willbe obtained. It will also be apparent that either half of the window maybe opened at will without interfering with the other half. It will alsobe apparent that a simple construction is provided which is both airtight and moisture proof when the window is in its closed position.

The means for locking the window in its closed or any other desiredposition will now be described.

Mounted on the meeting rails 23 and 24 on the interior side of thewindow are Cremorne bolts 40, particularly illustrated in Figs. 7 and 8.The Cremorne bolts comprise two slides 41 and 42 which enter housings 43secured to the meeting rails. These slides are moved simultaneouslyupward and downward by the rotation of a handle 44. When the windows arein their closed position and it is desired to lock them there thehandles 44 are pulled downward, the ends of the slides 41 and 42 movebehind keepers 45 and the window is locked so that it cannot be openedfrom the outside and will not vibrate due to the wind.

When either half of the window is fully opened or partially opened, aslight downward pull on the handles 44 will force the ends of the slides41 and 42 against the cross members 30 and positively lock the windowsin any desired position. In Fig. 5 the parts are shown in the positionthey would assume with the windows locked fully open and in Fig. 6 withthe windows locked in a partially open position.

Automatic locking means are provided at the juncture of the sections 15and 20. This automatic locking means comprises snap bolts 50,particularly shown in Figs. 9 and 10. These snap bolts are mounted iiithe side sash members 19 of the sections 20. These comprise housings 51having bolts 52 @.XQDCling upwardly and downwardly. These bolts arebeveled at their ends 54 and are spring pressed in a locking position bysprings 55. When the window is pulled closed the ends of the bolts willlatch past the lower frame members and enter openings 56. A handle 57operates a cam mechanism 58 so that when it is desired to open thewindow the handle 57 is manipulated, the snap bolts are Withdrawn andthe window pushed open.

It will be plain from the foregoing if the window were closed and theCremorne bolts weie not locked, the snap bolts would spring in place andprevent the window from being tampered with from the outside. It willlikewise be apparent from the foregoing that the window may be easilyand quickly locked in any desired position.

Pull handles 60 are secured to the sash members 19 to facilitate theclosing of the windows. The glass 61 may be secured in the sash membersin any well known manner.

Considering Figs. 2 and3, it is noted that there are two pairs offolding window-sashes, the members of each of which pair are indicatedby 15 and 20, at each side of the central meeting rails. Each sash 15 ishinged to a vertical frame member 11 at 13 so as to swing outwardly. Theinward vertical edged portion of each sash 15 has hinged to it at 18 asash 20, the hinged spindle of hinge 18 being on the inward side of eachpair so that each sash 20 may be swung inwardly and brought up againstthe outwardly swung sash 15 when the two sashes are in fully openposition. The hinged edge of each sash 15 is provided with the fiatextruded ribs 16 and the hinged inner vertical wall of each vertical jamb 11 is provided with corresponding flat extruded flanges. When eitheror both sashes 15 are j closed, these extruded ribs abut to formweathertight joints. The opposed hinged edges of each pair of sashes 15and 20 are similarly provided with extruded metal ribs that formcomplementary weatliertight abutments, when the two sashes are inalignment 1n closed position.

The inward free vertical edges of the frames of the two sashes 20 aresimilarly provided with extruded joint-forming ribs as above noted andthese ribs coming into cooprative contact, when the window is closed,form weathertight joints for the latter mentioned sash members whichform the vertical 1 meeting rails. It has been pointed out that in theopening and closing movements of each pair of sashes 15 and 20, the sashare guided at top and bottom by abutments extending either into an uppertrack groove or an under track groove 32; there being an upper and anunder track groove and each sash 20 being provided with an upper andunder roller or stud 36 which work in the track 32.

Each track is horizontally disposed and ex- I tends lengthwise of a topor bottom frame casing member, as the case may be.

It is an important feature of this invention to provide for the openingof either pair of sash by a push on the handle 60 in the outwarddirection. (See right hand of Fig. In such movement the extruded ribs onthe inward edge of the right hand meeting rail or member 24 is initiallywithdrawn by a very slight angular movement from its Contact with thecomplementary extruded ribs on the opposed meeting rail. On the otherhand, an outward push on the handle 60 of the left hand pair of sash 15and 20 would similarly withdraw at a slight starting angle the eX-truded ribs on the vertical edge of the left hand meeting rail, leavingthe right hand pair of sash in closed position. The slight )ogs 37referred to aid in securing the desired slightly angular withdrawingmovement of f one set of these extruded ribs from contact with theother.

The automatic locking devices including the snap bolts 50 are locatedfor each pair of hingedly connected sashes 15 and 20 in the outward edgeportion of an inward sash 20. These bolts automatically snap intolocking position (Fig. 10) and when either pair of hingedtogether sashesare brought into aligned closed position, that pair of sash isautomatically locked in position; and even if the Cremorne lockingdevices of the meeting rails are not moved into locked position, one orboth pairs of the hinged-together sashes 15 and 20 are certainly lockedin closed position.

Referring to Fig. 4, it is noted that the upper and under memberscontaining the tracks 32 are detaehably secured in place. These membersare indicated by 30 and are made detachable because when the track wallsbecome worn, themembers may be replaced. They also reinforce theadjacent window or doorway frame members. It is here noted that whilethe invention above described is referred to as an improvement inwindows, such Windows may be long doors with either glass` or solidpanels.

Various changes may be made in the details A invention. The membersreferred to as sash are in reality structures Which may be win.- dow ordoor frames oftransparent or solid material an d made of glazed Windowsor shutters r otherwise, as desired.

` What I claim is:

The combination with a stationary metal trarne having upper, under andvertical side edges; and the opposable vertical edges of the innerframes being eontactible, one with the other, when in aligned position;the members of each pair of frames being swingable into an outsideiiatwise, folded position; upppr and under lengthwise-extending straigt, metal,`lengthwise channeled guide tracks and metal, frame-carriedstuds projecting into the channels of the guide tracks and cooperatingwith walls thereof during the opening and closing movements of theframe; and an automatic locking device for each pair of frames saidguide tracks being detachably secured each to a stationary frame jamband also serving as a lengthwise and Widthwise reinforcementl thereof;side walls of the guide tracks being laterally jogged midway betweentheir ends for lateral movements of cooperating studs to securejoint-forming Contact without interference of the opposable edges of theinnermost movable frames.
